Why Does Stainless Steel Rust?
Stainless steel is a type of metal that is highly resistant to rust, however, it is not rust-proof. Rusting is still possible to occur under various environment, human mis-handling, or lack of regular maintenance. People often misinterpret stainless steel being rust-proof and neglect to perform regular maintenance. However, it is often too late or too tough to treat when the material has been polluted or rusted. Therefore, regular maintenance is absolutely vital to keep the material looking splendid; after all, prevention is better than cure. Stainless steel is an excellent anti-corrosive metal which contains chrome that forms a thin layer of natural coating on the surface when combining with oxygen in the air. This thin layer of natural coating has the benefit of anti-oxidization which aids the metal to prevent rusting, corroding, and serves as an extra protection to the surface of the material. There are various reasons or conditions causing stainless steel to rust. But in general, the iron, salt, acidic, or many other corrosive particles in the atmosphere around a particular area can result in the attaching or accumulating of such elements on the surface of the material, damaging and causing it to rust over time. Possible reasons or conditions that cause stainless steel to rust: (1) Construction sites or traffic areas that are filled with dust, dirt, iron powders, or other corrosive pollutants. (2) Areas with heavy automobile exhaust containing corrosive gas and pollutants. (3) Waste released by air conditioners or heaters. (4) Hot spring areas or volcanic areas with corrosive gas in the air. (5) Coastal, beach, or shore areas with salt particles carried by the sea breeze. (6) Chemical reaction from acidic or corrosive cleaning detergent. (7) Grease or dirt from fingerprints or handprints.
